| Hi,
Thanks for having a look. If fault and monitor are synonymous, I'm not sure why then, the unit would say the compressor is not on if L is hooked up. Seems strange? Is it possible the IAQ is actively monitoring (ie: attempting to query) the heat pump through L?
This t-stat is, apparently, a "version 2" unit. Indeed, the difference between the online instructions and my printed copy, includes, on mine, the indication of L for monitoring.

While I was noting these down, when I got to about 530, the light came on. When I hit Done, it flashed error 89 at me, then disappeared after a few moments. |
